Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipeline construction, in particular to a pipeline construction connection device for water supply and drainage. Background Art

[0002] Water supply and drainage engineering refers to the urban water supply system and drainage system. The main contents can be divided into water supply engineering and drainage engineering. Water supply engineering is an engineering facility built to meet the water needs of urban and rural residents and industrial production. Drainage engineering is a project that collects and discharges human domestic sewage and various wastewater, excess surface water and groundwater in production. Water supply and drainage pipelines are pipelines used to transmit water in water supply and drainage projects. There are many ways to connect water supply and drainage pipelines, including threaded connection, groove connection, flange connection, welding connection, hot melt connection, ferrule connection, compression connection and socket connection.

[0003] During the construction of water supply and drainage pipes, it is necessary to ensure that the centers of two water supply and drainage pipes are aligned. Two groups of construction workers are needed. One group of construction workers will manually set up and support the pipes, and the other group of construction workers will dock and assemble the pipes. During the center alignment process, the pipes need to be repeatedly moved left and right to ensure center alignment, which consumes a lot of manpower and has a high time cost. Therefore, a water supply and drainage pipe construction connection device is proposed to save time and effort during the drainage pipe construction process.

[0004] For example, the Chinese patent application with the publication number CN117028673A discloses a water supply and drainage pipeline construction connection device, which solves the problem that it is time-consuming and laborious to assemble the water supply and drainage pipelines and align the pipelines. The device includes a support frame, a fixed block, a driving mechanism and an adjusting mechanism. The fixed block is fixed in the support frame, a first support plate is fixed at the bottom of the fixed block, a first clamp is fixed at the bottom of the first support plate, a slider is provided in the support frame for sliding, a fixed frame is fixed at the bottom of the slider, a mounting frame is provided at the bottom of the fixed frame for rotation, a second support plate is symmetrically fixed at the bottom of the mounting frame, a second clamp and a third clamp are fixed at the bottom of the second support plate, a leg is provided at the bottom of the support frame, and a roller is provided at the bottom of the leg for rotation. The above-mentioned public document fixes one water pipe by the first clamp, fixes the other water pipe by the second clamp and the third clamp, and then adjusts the center line of the water pipe to coincide by the adjusting mechanism, drives the water pipe to rotate by the driving mechanism, facilitates the alignment of the flange holes on the water pipe, and combines the two water pipes together by the slider.

[0005] However, the clamping mechanism used to clamp and fix the pipes in the above-mentioned public documents is a clamp, which is used to clamp and fix the pipes that need to be connected on both sides. The clamping mechanism of a water supply and drainage pipe construction connection device can fit and clamp the pipe with a relatively fixed diameter. When the clamp needs to clamp pipes of other sizes, it is necessary to replace the water supply and drainage pipe construction connection device with a clamp of the corresponding size to achieve the purpose of fitting and clamping the pipe. During construction, it is necessary to prepare water supply and drainage pipe construction connection devices with clamps of various sizes for replacement. The clamping mechanism of a water supply and drainage pipe construction connection device cannot fit and clamp pipes of different sizes. Utility Model Content

One end of the stopper 604 close to the center of the fixed ring 602 extends out and presses against the surface of the pipe, so that the clamping mechanism 6 fixes the pipe, and at the same time, the stopper 604 extends out and presses against the surface of the pipe, so that the clamping mechanism can fit and clamp pipes of different sizes, thereby improving the scope of application of the clamping mechanism on the pipe construction connection device for water supply and drainage. The invention solves the technical problem that the clamping mechanism in the existing water supply and drainage pipeline construction connection device can fit and clamp the pipeline with a relatively fixed diameter, but cannot fit and clamp pipelines of different sizes.

The telescopic assembly 607 in this embodiment ensures that the abutment 604 is telescoped toward the center of the fixed ring 602.

The setting of the U-shaped plate 601 facilitates the two fixed rings 602 to be spaced at the same height, wherein the open end of the U-shaped plate 601 is the top of the U-shaped plate 601. At the same time, the setting of the U-shaped plate 601 makes the U-shaped opening groove on the U-shaped plate 601 fit with the stop block 604, providing space for the stop block 604 to expand and contract on the fixed ring 602, thereby avoiding the situation where the stop block 604 conflicts with the moving block 5 when expanding and contracting on the fixed ring 602.

The two moving blocks 5 are respectively threadedly connected to both ends of the bidirectional threaded rod 3, and one end of the bidirectional threaded rod 3 extends through the fixed block 2 and is connected to a rotating handle 4 at the extended end. Two guide rods 9 are fixedly connected between the two fixed blocks 2, and the two guide rods 9 are respectively arranged on both sides of the bidirectional threaded rod 3, and the moving block 5 is slidably connected to the guide rod 9. The rotating handle 4 is provided with anti-skid patterns 11 to play an anti-skid role. The guide rod 9 plays a reinforcing guiding role in the movement of the moving block 5, so that the moving block 5 and the clamping mechanism 6 are more stable when moving. Rotating the rotating handle 4 can drive the bidirectional threaded rod 3 to rotate. When the bidirectional threaded rod 3 rotates, the two moving blocks 5 will move relative to each other or move in the opposite direction. When docking the pipes on both sides, the handle 4 is rotated to drive the bidirectional threaded rod 3 to rotate, thereby driving the moving blocks 5 on both sides to drive the pipes abutting on the clamping mechanism 6 to move relatively until the connecting ports of the two pipes fit together, making it convenient for the staff to connect the two pipes.

Four mounting bolts 802 are provided at the top of the mounting plate 801 , and the device is fixed to the ground through the mounting plate 801 and the mounting bolts 802 , thereby increasing the stability of the device.

[0036] When using Example 10, taking the clamping mechanism described in Example 6 as an example, first, according to the specific height of the on-site installation, stretch the telescopic plate 701 and the telescopic sleeve 702 so that the fixing assembly 8 fits the ground, and then the height between the telescopic plate 701 and the telescopic sleeve 702 is limited by the circular hole 703 and the limit bolt 704, and then the device and the ground are fixedly installed by the mounting plate 801 and the mounting bolt 802.
